jrchambers,congratulations.I've enjoyed this thread from the beginning.It sounds like you did everything perfectly and what a beautiful bear.I'll just throw something out for you to think about,but those fight pictures look more like pre-breeding behavior to me and the other bear looks like a sow.
I don't think you said but, your bear was a boar?It seems way early for that behavior but it still looks that way to me.Just a thought.Maybe one of your buddies will find out for sure.
Great job!
